Music is intrinsic to Jewish Meditation. This has been so since the time of the Prophets, and it continues so until the present day. All Jewish forms of contemplation that I know (including Talmud study!) are accompanied by some kind of singing or melody. The traditional literature is replete with descriptions and explanations of the power of music.
Jewish Meditation comprises for the most part, contemplation of the Divine Names. I have attempted to construct the kind of music that you can listen to as you contemplate the letters of the Hebrew Aleph Bet, as they appear in the Divine Names, and as they are permutated and combined in the various meditation practices known as Yihudim or "Unifications"
The first state of constructing this music was to work out a Tonal Alphabet corresponding to the 22 Hebrew Letters. A letter is symbolized by a particular chord (or actually three tone interval) on the guitar rising from the lower tones (Aleph) to the higher tones (Yod). The letters Kaf through Qof and symbolized by variations of those first ten intervals, rising through the same space (so to speak) but using different values.
The last three letters (Resh, Shin and Tav) are chords played on the fifth fret and up.
Each chord or interval can be used to pick or strum the letters. Various vocal tones seem to follow naturally from listening to the intervals, and once a certain sequence of letters (like a Divine Name) is encoded musically, you can even extemporate over it arriving at a melody or theme that expresses that sequence, at least as it resonates with that particular individual.
The tones, intervals and melodies which have resulted so far do not sound like typical Jewish music. However, I am pleased to note that they sound something like the kinds of melodic lines used the the various Hazzanim at my Rebbe's Kabbalah Yeshiva
